Abstract
A thiol-free procedure for regioselective preparation of (Z)-β-alkenyl sulfides via a three-component reaction of aryl/alkyl halides, phenylacetylene, and potassium isopropylxanthate in the presence of copper iodide as a catalyst in polyethylene glycol is reported. In this study, a xanthate salt is used as an odorless source of sulfur. The reactions proceed in a one-pot and single-step pathway with the formation of the carbothionate intermediate identified using NMR data as well as exclusively forming the Z isomer.

Abstract
A KOH-promoted unusual deoxidative coupling reaction of β-sulfinyl esters with benzylic trimethylammonium salts to produce thioethers is discovered for the first time. If quaternary ammonium salts synthesized from enantiomerically enriched amines are adopted, highly enantiomerically enriched benzyl thioethers (>95-99% ee) with configurations opposite to those of the enantiomerically enriched amines are obtained.

Abstract
A simple and cost-effective one-pot parallel synthesis approach to sulfides, sulfoxides, and sulfones from thiourea was elaborated. The method combines two procedures optimized to the parallel synthesis conditions: alkylation of thiourea with alkyl chlorides and mono or full oxidation of in situ generated sulfides with H2O2 or H2O2-(NH4)2MoO4. The experimental set up required commonly used lab equipment: conventional oven and ultrasonic bath; the work up includes filtration or extraction with chloroform. The method was evaluated on an 81 member library of drug-like sulfides, sulfoxides, and sulfones yielding the compounds on a 30-300 mg scale. A small-scale synthesis of 2-(benzhydrylsulfinyl)acetamide (modafinil) utilizing our approach resulted in similar efficiency to the published procedures.
